Rechargeable battery information – TI-500 RF SS
The TI-500 RF SS contains an internal lead-acid rechargeable battery. Before using the indica-
tor for the first time, please charge the battery overnight.
The indicator’s battery should operate for about 85 hours if left on continuously. The display unit
is configured to power down after 5 minutes of inactivity but this parameter can be changed thru
the A10 menu setting.
The battery can be charged while ON or OFF and the indicator can be operated while it’s charg-
ing unless the state of charge is very low.
WHEN TO CHARGE THE INTERNAL BATTERY
The best time to charge the sealed lead-acid type battery is any time the indicator is not in use.
You need not wait for the Low Battery Indication – in fact it’s best that you don’t. Charging the
battery when not in use keeps the battery “fresh” and is the recommended way to manage it.
When the battery needs to be charged, the Low Battery Indicator will start blinking in the upper
left-hand corner of the display. The indicator may be used for an additional 2 minutes before it
automatically powers down. It is imperative that you charge the battery at this time to avoid
permanent damage.
HOW TO CHARGE THE INTERNAL BATTERY
1. Connect the charger (AC Adapter 12 VDC, 800mA) to the scale, and then plug the charger
into an AC outlet. Make sure that the AC voltage appearing at the wall outlet matches
the input voltage marked on the AC adapter.
2. After the charging period expires, unplug the charger from the AC outlet, then from the
scale. The scale is now ready for use under its own battery power.
NOTE: The charger may be left connected to the scale indefinitely without damage to the in-
ternal battery.
HOW LONG TO CHARGE THE INTERNAL BATTERY
In general, the battery should be allowed to charge a minimum of 1.5 hours for every hour of
use. If you discharge the battery below 50% and do not allow the proper time for charging,
you may start to notice a decline in the usage period. This is normal and eventually the bat-
tery must be replaced.
REPLACING THE BATTERY
The recommended practice when removing the battery is to disconnect the ground connection
(black) first, then the red terminal. This ensures that a short circuit will not occur from a battery
lead or fuse lead touching the grounded housing while disconnecting the other terminal. Similar-
ly, the ground should be connected last when installing a new battery.
The US government has classified the internal battery as hazardous waste. Do not place battery
into landfill. An automotive store or a local waste agency may accept the batteries for recycling.
